Ingredients

Instructions

  1. Step 1: Pat dry 4 rainbow trout fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper. Lightly dredge each fillet in 1/4 cup all-purpose flour, shaking off excess.
  2. Step 2: Heat 2 tbsp olive oil and 2 tbsp unsalted butter in a large skillet over medium-high heat until butter foams. Add trout fillets skin-side down and cook for 4 minutes until skin is crisp and golden.
  3. Step 3: Flip the fillets gently and cook for an additional 3 minutes until the fish flakes easily with a fork.
  4. Step 4: Remove fillets to a warm plate. Lower heat to medium, add remaining 2 tbsp butter, 1 clove minced garlic, 2 tbsp fresh lemon juice, and 2 tbsp chopped fresh dill to the skillet. Stir for 1 minute until butter melts and sauce thickens slightly.
  5. Step 5: Spoon the lemon-dill butter sauce over the trout fillets and serve immediately.

How do I store leftover Pan-Seared Rainbow Trout with Lemon-Dill Butter?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep salt from drying out.
